this law against "advocating genocide" is a very weird law in canada. in canada, we don't have "hate crimes" in the sense of it being against the law to hate people. i am a strong proponent of hating people. i'd rather see the government outlaw loving people and send dirty fucking hippies to jail for love crimes than have them get on the ass of cynics and recluses that rightfully hate the society, because the society is sick and the culture sucks, and is getting worse with more immigration from backwards societies. if we have to choose between criminalizing hate and criminalizing love, i'd vote for criminalizing love. there's nothing more fucking annoying than a goddamned christian. but that's not what this is about.
in canada, a judge can increase the sentence of an existing crime, like uttering threats, if it's determined that the motivation was hate. if you get caught spraypainting a synagogue, you'd get charged with vandalism, and might have an additional sentence if the judge thinks your vandalism was hate-related.
"advocating genocide" is consequently not what you call a hate crime in canada, but is a literal restriction on speech, similar to the thrown out laws against spreading fake news in zundel, which is leading precedent. this law has not been tested, yet. it is clear that a law against "advocating genocide" would be dead on arrival at the supreme court, citing zundel. in fact, the law itself seems to be a reaction to zundel. i would advise any legal professional, including police, to assume that the law is unconstitutional, but just hasn't been thrown out yet.
the last news entry in the case is that the guy was released on bail while he underwent a psychiatric hearing. i would expect these charges will be dropped, due to no chance of conviction, and prosecution not being in the public interest.
if you were going to in theory charge somebody with this, it would be intended for politicians seeking power. to arrest some idiot for posting on the internet is not consistent with a free society, and the police should be roundly condemned for doing so.
